Chang the voting system to Proportional Representation (PR)

We have seen politics take a shift in the UK, but I believe if we keep the same old voting system, then real change will not happen. Parliament must be more accountable to the people and the people must feel they can be a full member in the process. The recent ER referendum showed people what to be engaged with issues, but first past the post creates safe seats and people feel disenfranchised and don't bother voting. PR will give people the same connection as the referendum did.
